Re: URL +1, LSID -1

    Someone raised the question of whether the LSID Browser for Firefox 
looks up DNS SRV records during the resolution protocol. In functional 
terms, the answer is YES, it does.

    The cause of confusion is that the browser uses a web service 
somewhere else (at as of version 1.0.1) to do the 
lookup. That's because the Mozilla JavaScript toolkit doesn't provide 
SRV record lookup. Yes, it is a hack, but nevertheless it makes the 
client resolve LSIDs according to the specification.

    You can disable that lookup by unchecking a box in the LSID Browser 
configuration. In that case, the browser will try to look up the 
authority using regular DNS A records (that "only in code" fallback 
mechanism that someone else mentioned in this thread). You can also 
configure the browser to provide your own local mapping between 
authority identifications to authority host.

    I hope this clarifies the issue.
